Microsoft: April Windows Server 2025 update may fail to install

Microsoft is investigating an issue with the installation of the KB5082063 security update on Windows Server 2025 systems, where users are encountering the 0x800F0983 error code during the deployment of April 2026 cumulative updates. A service alert indicated that a limited number of servers may experience installation failures with this error. Additionally, some Windows Server 2025 devices may unexpectedly boot into BitLocker recovery mode after the update, requiring a BitLocker key, although this is unlikely to affect home users. Microsoft has also resolved a long-standing bug that caused Windows Server 2019 and 2022 systems to upgrade to Windows Server 2025 unexpectedly. Furthermore, Microsoft has released several emergency updates this year to address various security vulnerabilities, including issues with the Routing and Remote Access Service, Bluetooth device visibility, Microsoft account sign-ins, and installation challenges related to the March 2026 non-security preview update.

Microsoft to force updates to Windows 11 25H2 for PCs with older OS versions — ‘intelligent’ update system uses machine learning to determine when a device is ready

Microsoft is updating devices running Windows 11 version 24H2 to version 25H2, as support for 24H2 will end on October 13, 2026. The automatic update targets Home and Pro editions, while organizational devices are exempt. An "intelligent" system using machine learning will determine device readiness for the update, though details on the criteria remain unclear. Additionally, Microsoft released an emergency update, KB5086672, to address issues from a previous faulty update, KB5079391, which caused installation failures.

Windows 95 let installers trash its files then fixed the mess behind their backs

Microsoft veteran Raymond Chen discussed how Windows 95 handled installers that overwrote crucial system files. The operating system was designed to allow installers to compare version numbers, permitting overwrites only if the new file had a higher version. However, many installers ignored this rule, often replacing Windows 95 components with outdated Windows 3.1 versions, causing significant system issues. Windows 95's commitment to backward compatibility meant that preventing file operations could disrupt installers, leading to installation failures or error messages for users. To address these challenges, Microsoft created a hidden directory, c:windowssysbckup, to store commonly overwritten files. After an installation, Windows would check version numbers and replace lower versions with higher ones, maintaining system integrity despite third-party installer chaos.

Exit Windows S Mode Easily

Windows S Mode is a restricted version of Windows designed for entry-level devices, allowing only apps from the Microsoft Store to enhance security and performance. Users may find it limiting if they need software not available in the Store, such as gaming platforms or professional tools. Exiting S Mode is done through the Microsoft Store by searching for "Switch out of S Mode," clicking "Get" or "Install," confirming the switch, and waiting for the process to complete. This change is permanent, and users cannot revert back without a full reset or reinstallation of Windows. Important considerations before switching include ensuring a stable internet connection, checking the Windows edition, backing up data, and understanding the security risks involved. Common issues during the process include the missing option to switch and installation failures, which can often be resolved by restarting the PC or checking the internet connection. After leaving S Mode, users can install applications from outside the Microsoft Store but must be cautious about security.

How to Install McAfee Antivirus on Windows 11 or 10

Installing third-party antivirus software like McAfee on Windows 11 can be challenging due to the built-in Windows Security, which can complicate the installation process. Users may face issues such as silent failures from conflicting software, permission problems on restricted machines, or restrictions due to S Mode on new laptops. Windows 11 includes Windows Security, which is effective for malware protection, but McAfee may be necessary for compliance, additional features, or centralized protection for multiple devices. McAfee supports Windows 11 Home, Pro, and Education editions but not Enterprise. The minimum hardware requirements include a processor of 1 GHz or faster, at least 2 GB of RAM (4 GB recommended), 1.3 GB of free disk space, an internet connection for download and updates, and a display resolution of at least 1024×768. McAfee requires a persistent internet connection for activation and updates. Before installing McAfee, users should check if their device is in S Mode, as McAfee cannot be installed in this mode. They must remove any existing antivirus software completely, as leftover files can interfere with the installation. Users should also ensure that Windows 11 is up to date and verify that there is enough disk space available. To download McAfee, users should go directly to the McAfee trial page to avoid scams. After downloading, they need to run the installer and restart their computer after installation. Users should then activate McAfee, run a manual update, and conduct a full system scan. Common installation problems include freezes during download, errors due to S Mode, and issues with Windows Security not recognizing McAfee as the active antivirus. Users can verify that McAfee is functioning correctly by checking the system tray icon, Windows Security settings, and the McAfee dashboard. To uninstall McAfee, users should go to Settings > Apps > Installed Apps, select McAfee, and follow the prompts to remove it. After uninstallation, Windows Security will reactivate automatically. McAfee offers several plans for Windows users, including Basic, Essential, Premium, and Advanced, each with different features and device limits. The Basic plan is suitable for single-device users without additional needs, while families may benefit from the Essential or Premium plans.

Microsoft Refreshes Secure Boot Certificates via Windows Update

Microsoft will begin rolling out new Secure Boot certificates through Windows Update starting in March 2026, coinciding with the expiration of original certificates from 2011, which will phase out in June 2026. The new certificates include Microsoft Corporation KEK 2K CA 2023, Microsoft UEFI CA 2023, Microsoft Option ROM UEFI CA 2023, and Windows UEFI CA 2023. Not all Windows users will receive the update simultaneously; eligibility will focus on high-confidence devices with strong update histories. Newer PCs sold from 2024 will already have the 2023 Secure Boot certificates, while some devices may require additional firmware updates from their OEMs. PCs that do not receive the new certificates will still boot but will operate with diminished security, increasing vulnerability to exploits and compatibility issues with anti-cheat software and future Windows versions. Users on unsupported Windows versions will not receive the new certificates, leading to heightened security risks after June 2026.

Microsoft’s change to Appxsvc may slow some Windows 11 PCs

Microsoft is modifying core system settings for Windows 11 versions 24H2 and 25H2 by enabling the AppX Deployment Service (Appxsvc) to launch automatically upon boot-up, transitioning from a manual trigger system. This change was confirmed in the December 2025 "Patch Tuesday" update (KB5072033) for both Windows 11 and Windows Server 2025. The Appxsvc will now remain active in the background from the moment the computer powers on, regardless of Microsoft Store access, to enhance system stability and minimize app installation failures or update glitches. Microsoft warns against manually reverting this setting, as it could lead to malfunctions in Store apps and essential services. Analysts suggest this move aligns with a strategy for updating Microsoft Store apps directly through Windows Update.

Task Manager creator says Windows 11 has turned into a sales channel for all products

Dave Plummer, a retired Microsoft Windows engineer, shared a video discussing the dissatisfaction with Windows 11 among long-time users. He attributes this discontent to Microsoft's focus on integrating its own products into the user experience, which alienates loyal users. The shift began with Windows 10, which adopted a "Windows as a service" model and aimed to create a unified user base for monetization through cloud services. Windows 11 has further evolved into a platform that promotes Microsoft products over user experience, leading to intrusive advertising within the OS. Plummer suggests improvements, including a genuine "Pro Mode" for power users, a "privacy ledger" for telemetry transparency, and better options during setup. He emphasizes the need for Microsoft to refine the Windows experience to regain user trust.
